Why does it say "mi'Boker la'Erev Yukatu"?
Rashi: In one day they are minced and crushed. Ibn Ezra - this is like "ba'Boker Yatitz v'Chalaf." Devar Eliyahu - in the morning he is in his strength - afterwards he passes, like a shadow. This is one of three other shortcomings of man that our verse teaches.
Malbim: They will be stricken with afflictions for their sins for a short time, like from morning until evening.
What is the meaning of "mi'Beli Mesim"?
Rashi: They do not put to heart to repent to their Maker.
Ibn Ezra: He does not understand. This is like "v'Yasimu v'Yaskilu."
Devar Eliyahu: [After he dies], no one puts his name on his lips (mentions him).
Malbim: The short punishment is lest he be given a permanent punishment.
Who will perish forever?
Rashi: The verse is abbreviated. (It refers to Shochenei Vatei Chomer, which the previous verse discussed.)
Devar Eliyahu: Resha'im. For Tzadikim, "v'Nasati Lahem b'Veisi... Shem Olam."
Malbim (21): Punishment in this world is better than Kerisus of the Nefesh in the world to come. "La'Netzach" hints to loss of the eternal Nefesh.
